Abstract

Wheat as raw material for flour, is milled using a Fluted Roll in a Roll Mill machine. Fluted Rolls are made through a machining process that aims to obtain the desired shape, size, and level of surface roughness. This study aims to determine the material contained in Fluted Rolls and the process of making Fluted Rolls through machining processes, such as milling and scraping, as well as welding processes. The results of this study conclude the fluted roll machining process using steel medium carbon, namely JIS S45C and high alloy steel (High Alloy Steel) namely AISI 410, the milling process uses a vertical milling machine, and the scrap machining process uses a CNC (Computer Numerical Control) scrap machine in making flutes on the fluted roll surface. In the milling process using a blade diameter of 20 mm and a main spindle speed of 600 rpm, the machine's cutting speed is 37.68 mm/minute. Welding process on fluted roll aims to connect the milled shaft with the roller mill using TIG (Tungsten Inert Gas). In the scrap machining process, the feeding speed used is 9000 mm/minute and the chisel return speed to point 0 is 27132 mm/minute, resulting in a one-time feeding time of 14.24 seconds. The total time for working on fluted rolls with B3f specifications is the total flute 550, diameter 250 mm, length 1250 mm, and the slope of the flutes that form a spiral is 10% for 2 hours 10 minutes 53 seconds.

Abstract

Garbage is a problem of concern worldwide. Public awareness in disposing of waste that is not in its place causes various kinds of problems, one of the problems that occurs is in rivers or artificial canals. This is what makes many people create tools to make it easier to control improper waste disposal. One of the tools that was created was a garbage collector, in making the design of a garbage collection machine using solidworks software, Galvanized Steel material was used with a rod size of 30 x 30 x 2.6 (mm) as the frame. With a frame size of 1320 mm in length, 790 mm in width and 1133 mm in height. The results of the simulation using solidworks software on the frame of the garbage collection machine are to get the von misses stress value with a maximum stress value (MPa) and a minimum stress value of (MPa), for the displacement value with a maximum stress value of 0.61 mm and for a minimum stress value of 0.00 mm, the safety factor gets a value of 3.55 ul. In the comparison of solidworks and theoretical software values, the value for von misses stress is 0.04%, for displacement is 0.24%, and for safety factor is 0.20%.

Abstract

Welding Shield Metal Arc Welding is a process of joining two metals by utilizing heat from jumping electrodes at two different poles. In this welding technique, the connecting material or metal material (electrode) is metal that has been coated with flux (welding slag). This study aims to determine whether current variations affect the impact strength in the SMAW welding process. In this study, welding was carried out on the ST 41 material using the E 6013 electrode with electric current variants on the SMAW welding machine, namely: 60 A and 85 A, followed by the Charphy impact test used to determine the strength of the ST 41 steel connection. The results obtained with the ST41 200A material were 0.566 J/mm2 and for the ST41 210A material, it was obtained 1.662 J/mm2. With research showing that the greater the amperage, the greater the effort required in the Charphy impact test and the greater the amperage, the greater the value of the Charphy impact test.
